This example of a realistic steam locomotive in HO scale features all-new tooling with the correct boiler, tender, cab, etc. Featuring a factory-installed Quantum sound system with dual speakers, the C&O 2-10-4 model offers authentic engine sounds, synchronized chuff, engine whistle, bell, blower hiss, squealing brakes and more. Authenticity is the key with this and other model trains offered by BLI, and that extends beyond the visual rendering of the model trains to the sound.
